Some subdrivers make use of the global reference tpacpi_pdev during
initialization, which is called from the platform driver's probe.
However, after the commit 38b9ab80db ("platform/x86: thinkpad_acpi:
Move subdriver initialization to tpacpi_pdriver's probe.") this
variable is only properly initialized *after* probing and this can
result in a NULL pointer dereference.
In order to fix this without reverting the commit, register the platform
bundle in two steps, first create and initialize tpacpi_pdev, then
register the driver synchronously with platform_driver_probe(). This way
the benefits of commit 38b9ab80db are preserved.
Additionally, the commit 43fc63a1e8 ("platform/x86: thinkpad_acpi:
Move HWMON initialization to tpacpi_hwmon_pdriver's probe") introduced
a similar problem, however tpacpi_sensors_pdev is only used once inside
the probe, so replace the global reference with the one given by the
probe.

irq_domain_add_linear() is going away as being obsolete now. Switch to
the preferred irq_domain_create_linear(). That differs in the first

device_node. The first parameter is NULL here so nothing else needs to

"Fixes and new HW support.
The diff is a bit larger than I'd prefer at this point due to
unwinding the amd/pmf driver's error handling properly instead of
calling a deinit function that was a can full of worms.

- Fix error handling in amd_pmf_init_smart_pc()
- Fix missing hidden options for Smart PC

MAINTAINERS: Update Ike Panhc's email address
platform/x86/amd: pmf: Fix missing hidden options for Smart PC
platform/surface: aggregator_registry: Add Support for Surface Pro 11
platform/x86/amd/pmf: fix cleanup in amd_pmf_init_smart_pc()
There are a few problems in this code:
First, if amd_pmf_tee_init() fails then the function returns directly
instead of cleaning up. We cannot simply do a "goto error;" because
the amd_pmf_tee_init() cleanup calls tee_shm_free(dev->fw_shm_pool);
and amd_pmf_tee_deinit() calls it as well leading to a double free.
I have re-written this code to use an unwind ladder to free the
allocations.
Second, if amd_pmf_start_policy_engine() fails on every iteration though
the loop then the code calls amd_pmf_tee_deinit() twice which is also a
double free. Call amd_pmf_tee_deinit() inside the loop for each failed
iteration. Also on that path the error codes are not necessarily
negative kernel error codes. Set the error code to -EINVAL.
There is a very subtle third bug which is that if the call to
input_register_device() in amd_pmf_register_input_device() fails then
we call input_unregister_device() on an input device that wasn't
registered. This will lead to a reference counting underflow
because of the device_del(&dev->dev) in __input_unregister_device().
It's unlikely that anyone would ever hit this bug in real life.

The PMF driver allocates a shared memory buffer using
tee_shm_alloc_kernel_buf() for communication with the PMF-TA.
The latest PMF-TA version introduces new structures with OEM debug
information and additional policy input conditions for evaluating the
policy binary. Consequently, the shared memory size must be increased to
ensure compatibility between the PMF driver and the updated PMF-TA.
To do so, introduce the new PMF-TA UUID and update the PMF shared memory
configuration to ensure compatibility with the latest PMF-TA version.
Additionally, export the TA UUID.
These updates will result in modifications to the prototypes of
amd_pmf_tee_init() and amd_pmf_ta_open_session().

There are three variants of which Huawei released the first two
simultaneously.
Huawei Matebook E Go LTE(sc8180x), codename seems to be gaokun2.
Huawei Matebook E Go(sc8280xp@3.0GHz), codename must be gaokun3. (see [1])
Huawei Matebook E Go 2023(sc8280xp@2.69GHz), codename should be also gaokun3.
Adding support for the latter two variants for now, this driver should
also work for the sc8180x variant according to acpi table files, but I
don't have the device to test yet.
Different from other Qualcomm Snapdragon sc8280xp based machines, the
Huawei Matebook E Go uses an embedded controller while others use
a system called PMIC GLink. This embedded controller can be used to
perform a set of various functions, including, but not limited to:
- Battery and charger monitoring;
- Charge control and smart charge;
- Fn_lock settings;
- Tablet lid status;
- Temperature sensors;
- USB Type-C notifications (ports orientation, DP alt mode HPD);
- USB Type-C PD (according to observation, up to 48w).
Add a driver for the EC which creates devices for UCSI and power supply
devices.
This driver is inspired by the following drivers:
drivers/platform/arm64/acer-aspire1-ec.c
drivers/platform/arm64/lenovo-yoga-c630.c
drivers/platform/x86/huawei-wmi.c
Also thanks for reviewers' working. They have made this patch improve
a lot.
